Hawaiian Islands Humpback Whale National Marine Sanctuary Last Updated on 2014-07-10 16:22:15 The Hawaiian Islands Humpback Whale National Marine Sanctuary is one of 13 sanctuaries in the National Marine Sanctuary System created under the U.S. Marine Protection, Research and Sanctuaries Act. The sanctuary's goal is to promote comprehensive and coordinated management, research, education and long-term monitoring for the endangered humpback whale and its habitat. The Hawaiian Islands are the world's most isolated island archipelago, born of ancient volcanoes and inhabited by animals and plants derived from ancestors that found their way here over thousands of miles of ocean. According to scientists, the shallow, warm waters surrounding the main Hawaiian Islands constitute one of the world's most important habitats for the endangered humpback whale. Nearly two-thirds of the entire North Pacific population of humpback whales migrates to Hawai`i each winter. Here,... More »

Monterey Bay National Marine Sanctuary Last Updated on 2014-07-10 15:23:34 The Monterey Bay National Marine Sanctuary (MBNMS), designated in 1992, is a Federally-protected marine area offshore of California's central coast. Stretching from Marin to Cambria, the MBNMS encompasses a shoreline length of 276 miles and 5,322 square miles of ocean, extending an average distance of 30 miles from shore, extending from Rocky Point (just north of San Francisco's Golden Gate Bridge) to Cambria (just north of Morro Bay). At its deepest point, the MBNMS reaches down 10,663 feet (more than two miles). It is the USA's eleventh Marine Sanctuary and second only to the Northwestern Hawaiian Islands Marine National Monument in size—larger than Yosemite or Yellowstone National Parks. The MBNMS was established for the purpose of resource protection, research, education and public use. Its natural resources include the USA's largest kelp forest, one of... More »
Gray’s Reef National Marine Sanctuary Last Updated on 2014-07-08 18:36:18 Within the 17-square-nautical-mile sanctuary, there are both rocky ledges and sandy flat places. The reefs' rock ledges, submerged beneath 60 to 70 feet of water, can be as tall as 6-8 feet and are highly complex, with nooks and crannies that provide habitat for invertebrates and fishes to hide. The attached invertebrates form a dense carpet of living creatures that in places completely hides the rock. This feature gives the habitat of Gray's Reef its common name -- a "live bottom." Gray's Reef National Marine Sanctuary, designated in January 1981, is one of the largest near-shore live-bottom reefs in the southeastern United States. The sanctuary is located 32 kilometers (17.5 nautical miles) off Sapelo Island, Georgia and encompasses 58 square kilometers (17 sq. nautical miles) of live-bottom habitat. It is one of 13 marine sanctuaries that make up the... More »
Elkhorn Slough National Estuarine Research Reserve, California Last Updated on 2014-07-01 16:13:44 The Elkhorn Slough National Estuarine Research Reserve is one of 27 National Estuarine Research Reserves established nationwide as field laboratories for scientific research and estuarine education. Elkhorn Slough is one of the relatively few coastal wetlands remaining in California. The main channel of the slough, which winds inland nearly seven miles, is flanked by a broad salt marsh second in size in California only to San Francisco Bay. The reserve lands also include oak woodlands, grasslands and freshwater ponds that provide essential coastal habitats that support a great diversity of native organisms and migratory animals. More than 400 species of invertebrates, 80 species of fish and 200 species of birds have been identified in Elkhorn Slough. The channels and tidal creeks of the slough are nurseries for many species of fish. At least six threatened or endangered species... More »
